(a) The commission shall not approve or conditionally approve a change of organization or reorganization that would result in the annexation to a city of territory that is within a farmland security zone created pursuant to Article 7 (commencing with Section 51296) of Chapter 7 of Division 1 if that city provides or would provide facilities or services related to sewers, nonagricultural water, or streets and roads, unless the facilities or services provided by the city benefit land uses that are allowed under a farmland security zone contract and the landowner consents to the change of organization or reorganization.

(1) If the farmland security zone is located within a designated, delineated area that has been approved by the voters as a limit for existing and future urban facilities, utilities, and services.

(3) If the landowner consents to the annexation.
(b) This section shall not apply during the three-year period preceding the termination of a farmland security zone contract under Article 7 (commencing with Section 51296) of Chapter 7 of Part 1 of Division 1.
